Systems Application ArchitectureAn application architecture used to develop applications for the IBM System Network Architecture (SNA) environment. Through Common User Access (CUA) architecture guidelines, Common Programming Interface (CPI) definitions, and Common Communications Support (CCS) protocols and conventions, SAA provides a basic structure for developing applications that are consistent across systems, including microcomputers, minicomputers, and mainframes.

A well-defined process used to recover "deleted" files. Rather than immediately freeing the disk blocks for a deleted file, Novell Storage Services (NSS) marks the name as deleted. Only when the space of the deleted file is needed is the file actually purged from the system. By using zMODE_DELETED to augment the source name space on zRename, you can recover deleted files.

A tool in NetWare Administrator for recovering files that were deleted but not yet purged from a NetWare volume.

A Open Source based printer and file replacement for Windows NT, 2000 and 2003 server.

Storage area networkIn ZENworks Server Management, clustered nodes together with their shared disk system and shared volumes.

1. Service Advertising Protocol: A protocol used by NetWare Loadable Modules (NLMs) to inform clients of a server's presence. Servers advertise their services, by both name and type, with Service Advertising Protocol (SAP), allowing routers to create and maintain a database of current internetwork server information. This information goes to all nodes on an IPX network.2. service access point: A virtual port on a data link adapter. A SAP provides communication points between adjacent local area network (LAN) protocol layers. A SAP is referred to by a three-digit hexadecimal number.3. secondary audio program.

Simple Authentication Security LayerA method for adding authentication support to connection-based protocols. To use this specification, a protocol includes a command for identifying and authenticating a user to a server and for optionally negotiating a security layer for subsequent protocol interactions. It is used with popular Internet protocols such as POP3, IMAP, SMTP, and LDAP.The LDAP v3 protocol uses the SASL to support pluggable authentication. The LDAP v2 protocol does not support the SASL.

A NetWare Loadable Module (NLM) in Storage Management Services (SMS) which a NetWare server uses to provide backup and restore capabilities. It is used to back up data across the network.

1. System Bus DriverIn PCI Hot Plug technology, software that

• Abstracts the platform-specific implementation of a PCI Hot Plug system
• Controls the system hardware necessary to perform hot plug functions
• Enables or removes power from a hot plug slot upon request
• Configures hardware by assigning resources such as memory, PCI, and interrupts of PCI adapters in hot plug slots

Split-brain Detector PartitionThe SBD Partition is a small space (usually 15MB or less) on a SAN where each node writes a packet to let others know it's "alive." If a node does not write its "I'm alive" packet within a configurable time, known as the heartbeat, then the node with the Master IP address will ping that node. If the node does not respond, the Master IP address node will send the "failed node" a "poison pill" packet, which tells the failed node to ABEND.

The ability to expand a computing solution to support increasing numbers of users without impacting performance. In NetWare, it is the incremental increase in throughput, or work accomplished relative to processor 0, when additional processors are brought online.

In ZENworks Desktop Management and ZENworks Server Management, a feature which adjusts the remote console screen size, thus allowing the remote operator to view the entire desktop of the managed workstation or server.

In ZENworks Server Management, a Server Inventory component that collects the .str files and stores them in the scan directory (scandir) at the Inventory server. The .str files are transferred using the XML-RPC protocol.

A feature of many disk drivers that improves the performance of disk reads and writes by combining many small I/O requests into one. If data is to be written to sequential locations on disk, the driver "gathers" the data from different locations in RAM and combines the data into one write. If data is to be read from sequential locations on disk, the driver executes one read and then "scatters" the data to different locations in RAM.

In ZENworks Desktop Management, a policy that sets up schedules for specific actions. This policy is contained in both the User package and the Workstation package.

In ZENworks Server Management, a plural policy that automates when and how a server goes down, and specifies whether it should be automatically brought back up. This policy is contained in the Distributed Server Package.

In ZENworks Desktop Management and ZENworks Server Management, a ZENworks utility that performs operations or enforces policies on a user-defined schedule. This utility runs on the inventoried workstation (wmsched.exe), inventoried server, and Inventory server. For example, the Scheduler runs the inventory scanner.

In ZENworks Server Management, the process of configuring the four different distribution schedules to provide for processing a Distribution. The schedules are Refresh (Distributor object), Build (Distribution object), Send (Channel object), and Extract (Subscriber object).

An instance in time that is arbitrarily selected as a point of reference for the Novell Directory Services (NDS) database. When a schema epoch is declared, the master replica of the [Root] partition is contacted and illegal time stamps on the schema record are repaired. Then a new epoch for the schema is declared on that server. All other servers receive a new copy of the schema, which includes the repaired time stamps.

The synchronization of modifications made to Novell Directory Services (NDS) schema data among all the replicas in the tree. Synchronization is necessary to maintain the consistency of the schema information throughout the NDS tree.

The http://www.sifinfo.org/. Connecting the applications with a common framework allows you to enter information once in an authoritative information source, such as a student information system, and then publish that information so other systems can be updated automatically.">Schools Interoperability Framework (http://www.sifinfo.org/.">SIF) is an industry initiative to develop an open specification for ensuring that K-12 instructional and administrative software applications interact and share data seamlessly. SIF is not a product, but rather an industry-supported technical blueprint for K-12 software. For additional information about SIF, see the Schools Interoperability Framework Web site at http://www.sifinfo.org/. Connecting the applications with a common framework allows you to enter information once in an authoritative information source, such as a student information system, and then publish that information so other systems can be updated automatically.

An XPath specification that provides an easy way to access data from your Web applications. exteNd Director includes a group of predefined scoped paths that are available from the Page Flow and Workflow Modelers and through the scoped path API.Scoped paths combine the concepts of application scope and physical location. Application scope refers to the state of the data, or data persistence. Data is nonpersistent if it is available to a single user for a single session. Data is persistent if it is available to one or more users over multiple sessions, and potentially to external applications. A scope also defines what application objects can access data. For example, exteNd Director defines a Flow scoped path that is accessible to any object in a given PageFlow or Workflow.A path is the physical location of the data. exteNd Director defines a path syntax for a set of predefined scoped paths. This syntax is based on XPath and includes support for XPath expressions and functions.

In ZENworks Desktop Management, an option available when performing imaging operations on a workstation. It lets administrators customize the imaging procedure by specifying imaging commands in a script.

Small Computer Systems InterfaceAn industry standard that provides high-speed access to peripheral devices such as hard disk drives, tape drives, and other hardware components. Computers and peripheral devices designed to meet SCSI specifications have a large degree of compatibility. SCSI is often implemented in servers and other high-level machines because of its high-speed performance.

Small Computer Systems Interface busAn interface that connects additional host bus adapters (HBAs) to controllers and hard disks. A SCSI bus is identified by its 50-pin connector (as opposed to an IDE bus, which has a 40-pin connector).

In ZENworks Desktop Management, ZENworks Handheld Management, and ZENworks Server Management, a policy used to minimize tree walking by specifying how far up the tree ZENworks will search for effective policies. This policy is contained in the Container Package.2. In ZENworks Server Management, a policy used to enable the Distributor Agent to locate and use policies in the Service Location Package for the purpose of writing reporting information to the database file.Most ZENworks Server Management policies are distributed rather than associated for enforcement.

Search Scope states how much of the search base to search.

Provides the ability to search content using conceptual pattern matching.

The System Fault Tolerance (SFT) III server that is activated after the primary server is activated.The secondary server mirrors the primary server, provides split seeks, and acts as a router for the local network segments to which it is directly attached (if the primary server isn't attached to those segments). The secondary server cannot do any additional work because it uses all its CPU cycles to keep current its mirror of the primary server. If the primary server fails, the secondary server becomes the primary server.

Encryption protocol for transferring HTTP data. SSL governs the exchange of information between two devices using a public key encryption system. SSL establishes and maintains secure communication between SSL-enabled servers and clients across the Internet.

The initial communication between an SSL server and client. At this stage, they agree on a protocol version, select cryptographic algorithms, optionally authenticate each other, and optionally generate a shared secret.

In ZENworks Desktop Management, a security option that runs an application in the system space as the Windows system user instead of in the user space as the logged-in user, so that locally installed applications can run even if the user has limited file system rights. The application's interface is not displayed to the user and the application is visible only in the Task Manager.

Short for "Security Equal To property."

An optional, multivalued property that lists the users that are granted security equivalence to this object. Each value must be a complete name.

An optional, multivalued property that lists the objects that the user is granted security equivalence to. It does not list implicit security equivalences, such as parent containers and the [Public] trustee. Each value must be a complete name.

A Novell Directory Services (NDS) feature that allows a user to possess all the rights of another object. Only users can have security equivalence. A user is automatically security-equivalent to the Groups and Organizational roles that he or she belongs to, and is implicitly security-equivalent to the [Public] trustee and to each container above the user in the tree, including [Root]. A user is explicitly security-equivalent to the objects listed in his or her Security Equals property.

In ZENworks Server Management, the schedule for the Channel object, which determines when the Distributor can begin sending its Distributions to the Subscriber servers that are subscribed to the Channel.

A NetWare DOS Requester module that enhances the IPX protocol by supervising data sent out across the network.SPX verifies and acknowledges successful packet delivery to any network destination by requesting a verification from the destination that the data was received. The SPX verification must include a value that matches the value calculated from the data before transmission. By comparing these values, SPX ensures not only that the data packet arrived at the destination, but that it arrived intact.

The transmission of data between devices over a single line, one bit at a time. NetWare uses the RS-232 serial communication standard to send information to serial printers, remote workstations, remote routers, and asynchronous communication servers.

An Internet protocol used to run IP over serial lines, such as telephone circuits or RS-232 cables, to interconnect two systems. SLIP allows users to use dial-up connections as Internet connections. Internet SLIP is being replaced by the Point-to-Point Protocol (PPP). Also called Serial Line IP.

A mouse that is designed to be connected to a computer's serial port. A serial mouse can be easily identified by the rectangular-shaped connector at the end of its cable.
